parameters. Used to create simple logic networks, ie. output do0.2 is only if do1.0 and
do1.1 is active. For more complex networks ask for the optional, integrated PLC
01: destination
(value range DO0.0 to DO8.0)
Selects the physical output of the signal
02: process ID
(value range a to f )
following parameters apply on selection PRZ only:
03: channel source
(value range CH00 to TA19 )
Selects the control channel (loop) used to drive the output. The options MX../A resp.
MX../G are the outputs of the air / gas mixer (for combustion units)
04: output charact
(value range 0 to 5)
Specifies the operation range of the output. Used to limit an output assigned to a
heating / cooling loop (range +100% to !100%) to the physical range of operation. In an
typical application one output (eg. controlling the heating elements) is set to "0 to
+100%" and a 2nd output (eg. controlling a fan) is set to "0 to !100%" (both outputs
assigned to the same control channel). The available settings are 0=0% to +100% /
1=+100% to 0% / 2=0% to !100% / 3=!100% to 0% / 4=!100% to +100% / 5=+100% to !
100%. The further settings will repeat the choices but use the motor characteristic for
non!linear devices: 6 to 11: motor char.#0 / 12 to 17: motor char.#1 18 to 23: motor
char#3 etc.
05: outp.% on IDLE
(value range 0 to 100)
Whenever the controller is IDLE the output is fixed to this value
06: outp. % on ERR
(value range 0 to 100)
Whenever the entire controller is in ERROR status the output is fixed to this value.
Note that this only applies on system errors and not an operation error on a single
channel
07: min. output %
(value range 0 to 100)
Lower output signal limit. The output will never drop below this limit. Can be used for
instance to obtain permanent minimum heating. Care should be taken since high
operating instructions bentrup TC-S2 V1.1
settings might interfere with the control loop
08: max. output %
(value range 0 to 100)
Upper output signal limit. The output will never exceed this limit. Can be used for
instance to limit the maximum heating of a kiln. Note that limiting can cause problems
if the applications lacks of heating power (gradient check errors etc.)
09: cyclus time
(value range 1 to 100)
Cyclus time (seconds) of the digital output. The output value is converted into an ON
and OFF period accordingly (T on + T off = T cyclus). Decreasing the cyclus time
improves accuracy but might decrease lifetime of the heating device. A typical value
for contactors on kilns is 30. Set to 0 for the Logic Output Option (different hardware).
A signal 1 Hz PWM 0!100% for solid state relays is provided on the output
following parameters apply on selection MOT only:
13: channel source
(value range CH00 to TA19 )
Selects the control channel (loop) used to drive the output. The options MX../A resp.
MX../G are the outputs of the air / gas mixer (for combustion units)
14: output char.
(value range 0 to 30)
Specifies the operation range of the output. Used to limit an output assigned to a
heating / cooling loop (range +100% to !100%) to the physical range of operation. In an
typical application one output (eg. controlling the heating elements) is set to "0 to
+100%" and a 2nd output (eg. controlling a fan) is set to "0 to !100%" (both outputs
assigned to the same control channel). The available settings are 0=0% to +100% /
1=+100% to 0% / 2=0% to !100% / 3=!100% to 0% / 4=!100% to +100% / 5=+100% to !
100%. The further settings will repeat the choices but use the motor characteristic for
non!linear devices: 6 to 11: motor char.#0 / 12 to 17: motor char.#1 18 to 23: motor
char#3 etc.
15: outp.% on IDLE
(value range 0 to 100)
Whenever the controller is IDLE the output is fixed to this value
16: outp.% on ERR
(value range 0 to 100)
Whenever the entire controller is in ERROR status the output is fixed to this value.
